ABOUT THIS IMAGE:

In celebration of the 17th anniversary of the launch and deployment of NASA's Hubble
Space Telescope, a team of astronomers is releasing one of the largest panoramic images
ever taken with Hubble's cameras. It is a 50-light-year-wide view of the central region of the
Carina Nebula where a maelstrom of star birth - and death - is taking place.

Hubble's view of the nebula shows star birth in a new level of detail. The fantasy-like
landscape of the nebula is sculpted by the action of outflowing winds and scorching
ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these
stars are shredding the surrounding material that is the last vestige of the giant cloud from
which the stars were born.

The immense nebula contains at least a dozen brilliant stars that are roughly estimated to
be at least 50 to 100 times the mass of our Sun. The most unique and opulent inhabitant is
the star Eta Carinae, at far left. Eta Carinae is in the final stages of its brief and eruptive
lifespan, as evidenced by two billowing lobes of gas and dust that presage its upcoming
explosion as a titanic supernova.

The fireworks in the Carina region started three million years ago when the nebula's first
generation of newborn stars condensed and ignited in the middle of a huge cloud of cold
molecular hydrogen. Radiation from these stars carved out an expanding bubble of hot gas.
The island-like clumps of dark clouds scattered across the nebula are nodules of dust and
gas that are resisting being eaten away by photoionization.

The hurricane blast of stellar winds and blistering ultraviolet radiation within the cavity is now
compressing the surrounding walls of cold hydrogen. This is triggering a second stage of
new star formation.

Our Sun and our solar system may have been born inside such a cosmic crucible 4.6 billion
years ago. In looking at the Carina Nebula we are seeing the genesis of star making as it
commonly occurs along the dense spiral arms of a galaxy.

The immense nebula is an estimated 7,500 light-years away in the southern constellation
Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the
Argonauts, from Greek mythology).

This image is a mosaic of the Carina Nebula assembled from 48 frames taken with
Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken
in the light of neutral hydrogen. Ground-based images taken at the Cerro Tololo Inter-
American Observatory in Chile were also used.
